Description
Technical field
The utility model relates to a kind of shell-and-tube heat exchanger.
Background technology
When using Water-heating shower, the waste water producing is directly arranged conventionally into sewer, and because wastewater temperature is still higher, heat contained in waste water is wasted, and does not meet energy-conserving and environment-protective theory.
For utilizing waste water institute heat content, at sewer bakie place, bathroom mounting heat exchanger.This heat exchanger one end is connected with water supply line, and the other end is connected with water heater or mixed water valve.When shower waste is flowed through this heat exchanger, heat first can be passed to heat exchanger, then be passed to the running water that temperature is lower.By improving like this running water temperature, reduce the output of water heater energy, thereby reach the object of energy-conserving and environment-protective.
On market, for reclaiming the heat exchanger of waste water residual heat, be mainly: around tubular type, fin-tube type or board-like, but conventionally there is more shortcoming in these heat exchangers, and major embodiment is:
1, amount of parts is many, complex structure, and manufacturability is poor.
2, overall appearance is poor, and moulding is not attractive in appearance.
3, a little less than strength of parts, yielding, during use, protection network must be installed.
4, fin-tube type, plate type heat exchanger, waste water runner gap is narrow, easily stops up in (as hair, mud etc.), and easy-clear not, maintainable poor.
5, wound tube heat exchanger, effective heat exchange area is few, and heat transfer effect is poor.
